Self study plan for understanding nutritional processes

I've got a good background in physics and math. I'm interested in getting a decent foundation in chemistry/biology with an eye towards understanding nutrition (for starters). (I've been out of school for years.)

From browsing course requirements, it seems like I'll need: organic chemistry, molecular biology, then biochemistry. From there, I should have the necessary pre-reqs for jumping into the nutritional texts.

Is this reasonable? Am I missing anything?

So far I'm working thru Clayden (et al) Organic Chem. Then I plan to move to Albert's (et al) Molecular Biology of the Cell. Then probably Voet/Voet for Biochem.
